Shloka 51
अधरोत्तरमेतद् वा लोकानां वा पराभव: । यदिमौ जीवत: कृष्णौ कालो हि दुरतिक्रम:,“इस (आग्नेय) अस्त्रके प्रभावमें कोई उलट-फेर तो नहीं हो गया अथवा सम्पूर्ण लोकोंका पराभव होनेवाला है, जिससे ये दोनों कृष्ण जीवित बच गये। निश्चय ही कालका उल्लंघन करना अत्यन्त कठिन है
sañjaya uvāca | adharottaram etad vā lokānāṃ vā parābhavaḥ | yad imau jīvataḥ kṛṣṇau kālo hi duratikramaḥ ||
サञ्जयは言った。「この（アーグネーヤ）武器の働きに何か逆転が起きたのか。それとも諸世界そのものが敗北へと定められているのか——ゆえにこの二人の『クリシュナ』が生き残ったのか。まことに時（カーラ）を越えることはきわめて難しい。」

The verse underscores the Mahābhārata’s recurring ethic that human power—including the most fearsome weapons—operates within the larger sovereignty of Kāla (Time/Fate). When outcomes defy expectation, the narrative points to an overriding cosmic order that is difficult to transgress.
Sañjaya, reporting events, expresses astonishment that the Agneya weapon has not destroyed the intended targets: the two ‘Kṛṣṇas’ (commonly Kṛṣṇa and Arjuna). He wonders whether the weapon’s effect has been reversed or whether a world-shaking destiny is at play, concluding that Kāla is not easily overcome.
